WeChat Group Summary

WeChat Group Summary

群聊精华提取专家。把零散的微信群聊记录提炼成结构化、可读性强的简报，并维护跨次运行的群聊历史与群友画像。底层依赖外部 wx-cli 二进制（wx 命令），不打包脚本。

⚠️ Sandbox restriction

wx-cli reads from ~/.wx-cli/ (config, cache, daemon socket) and from WeChat's data directory (~/Library/Containers/com.tencent.xinWeChat/ on macOS). Both paths are outside Claude Code's default sandbox. Every wx command in this skill needs to run with dangerouslyDisableSandbox: true from the start — don't waste a sandbox attempt first. The user can use /sandbox to view/edit restrictions.

User Input Tools

When this skill prompts the user, follow this tool-selection rule (priority order):

1. Prefer built-in user-input tools exposed by the current agent runtime — e.g., AskUserQuestion, request_user_input, clarify, ask_user, or any equivalent.
2. Fallback: if no such tool exists, emit a numbered plain-text message and ask the user to reply with the chosen number/answer for each question.
3. Batching: if the tool supports multiple questions per call, combine all applicable questions into a single call; if only single-question, ask them one at a time in priority order.

Concrete AskUserQuestion references below are examples — substitute the local equivalent in other runtimes.

Prerequisites

Before invoking the workflow, verify the environment. Run these checks in order; stop at the first failure and surface the exact next command the user needs.

1. wx-cli installed — run wx --version. If missing, tell the user to install it themselves (npm install -g @jackwener/wx-cli or use one of the alternatives at https://github.com/jackwener/wx-cli). Do NOT auto-install — this repo forbids piped/silent installs.
2. ~/.wx-cli directory owned by the current user — sudo wx init historically chowned this directory to root, which breaks every subsequent non-sudo wx call. Check:

   ls -la ~/.wx-cli/ 2>/dev/null | head -5
   

   If the directory exists but the owner is root (or anything other than $(whoami)), tell the user to repair it themselves:

   sudo chown -R $(whoami) ~/.wx-cli
   sudo rm -f ~/.wx-cli/daemon.pid ~/.wx-cli/daemon.sock
   wx daemon start
   

   The skill should NOT run sudo on the user's behalf.
3. wx-cli initialized — wx sessions should return data. If it fails with "no keys" / "init required", instruct the user to run wx init while WeChat is running (on macOS, codesign --force --deep --sign - /Applications/WeChat.app first). Prefer non-sudo init; only fall back to sudo wx init if the user's wx-cli version requires it — and warn them that they'll need step 2's chown after.
4. WeChat 4.x running and logged in — required for the daemon to find data files.

Preferences (EXTEND.md)

Check EXTEND.md in priority order — the first one found wins:
